Oxygen Measurement Controllers

A range of controllers is available. These provide different levels of sophistication in the measurement of oxygen enabling the selection of the most appropriate and cost effective configuration for an application or the working environment.


Digital Model 10

The Model 10 is designed as an integrated unit to make oxygen measurements. The standard version includes an electronic magnetic stirrer and the electronics to supply the polarising voltage, signal amplification and digital display of percentage saturation. The only additional requirement is a supply of constant temperature water to the incubation chamber to ensure accurate readings.

Digital Model 10

Located on the front panel are controls to:

At the rear a socket provides a 0-1V output suitable for a data logger, chart recorder or other device.

A range of oxygen electrodes is available to meet the needs of different applications.

Technical Data

Resolution:
0.1% saturation.
Polarising Voltage:
0-1V.
Recorder Output:
0-1V via BNC connector.
Stirrer:
120-1200 rpm.
Power Supply:
110/120V or 220/240V AC; power cord supplied.
Size:
230mm (w) x 300mm (d) x 200mm (h).
Weight:
2.5kg.

Dual Digital Model 20

The Model 20 is a two channel version of the Model 10. The single digital display of percentage saturation is switchable between either channel, while the two output sockets allow simultaneous monitoring of both channels. The only additional requirement is a supply of constant temperature water to the incubation chamber to ensure accurate readings.

Dual Digital Model 20

Located on the front panel are controls to:

At the rear, two sockets provide 0-1V outputs suitable for a data logger, chart recorder or other device.

Combined Polarising Circuit and Readout Meter

Combined Polarising Circuit and Readout Meter

The Combined Polarising Circuit and Readout Meter provides an analogue alternative to the Digital system. The unit is battery operated and has two analogue meters which simultaneously display polarising voltage and oxygen levels. The controls allow adjustment of the polarising voltage, calibration of the electrode and enable the unit to be used without the oxygen meter reading (when being used with a chart recorder for instance). Two DIN sockets are located on the front panel for the electrode and connection to a chart recorder. A stirrer is not included.

Technical Data

Resolution:
2% saturation.
Polarising Voltage:
0-1.5V.
Recorder Output:
0-30mV.
Stirrer:
Not included.
Power Supply:
1 x C type and 2 x PP3 type batteries supplied.
Size:
280mm (w) x 170mm (d) x 70mm (h).
Weight:
1.4kg.

Polarising Circuit

Polarising Circuit

This simple, low cost, battery operated unit supplies the polarising voltage and produces an analogue output for a chart recorder.

The controls allow the polarising voltage (which is displayed on a meter) to be adjusted. The recorder output voltage is adjusted by a five position, coarse adjustment switch and a ten-turn fine potentiometer which enables the electrode to be calibrated to the recorder. The electrode and the recorder are connected via DIN sockets on the front panel. A stirrer is not included.

Technical Data

Resolution:
n/a.
Polarising Voltage:
0-1.5V.
Recorder Output:
0-30mV.
Stirrer:
Not included.
Power Supply:
1 x C type battery supplied.
Size:
200mm (w) x 120mm (d) x 70mm (h).
Weight:
0.8kg.

Ordering Information

For a working oxygen measurement system it will be necessary to have an electrode and a controller (some controllers may also require a separate stirrer). Rank Brothers have a range of oxygen electrodes suitable for use with these controllers.
